  About the stability of Au(NH3) 4 3+ in aqueous solution

  摘要：

  The transformations of Au(OH)(4)(-) in aqueous solutions (T = 20 degrees C, I = 1) containing NH3 and NH4+ pH 8.1-8.5) were studied. The most pronounced changes in the system occur in the range 0 > log[NH4+] > -2.0 (c(Au) = 1-10) x 10(-4) mol/L, the monitoring time was about two weeks). When log[NH4+] < -2.0 no changes in the spectra observed, probably, because of the very low rate of the processes. As c(Au) increases in the indicated range, the polymerization rate grows. The equilibrium constant for Au(NH3)(3)OH2+ + NH3 = Au(NH3)(4)(3+) + OH is log K-4 OH,K-NH3 = -4.2 +/- 0.3. This constant was used together with other constants, taking into account possible ligand effects, to estimate the formation constant of Au(NH3)(4)(3+) : log beta(4) = 47 +/- 1 E-3/0 = 0.64 +/- 0.02 V, log beta(4) (OH,NH3) = -8.5 +/- 1 (substitution of 4 NH3 for 4 OH- in Au(OH)(4)(-)), log beta(4) (C1,NH3) = 17.5 +/- 1 (substitution of 4 NH3 for 4 Cl- in AuCl4-).
